JOHN BAGGS, OF BALTIMORE, MARYLAND, ASSIGNOR OF ONE-HALF TO CHARLESSHIPLEY, OF SAME PLACE.

SOFA-BEDSTEAD.

SPECIFICATION forming part of Letters Patent No. 294,954, dated March11, 1884.

Application filed August 17, 1883.

To all whom it may concern.- v

Be it known that I, JOHN BAGGS, a citizen 'of the United States,residing in Baltimore city and State of Maryland, have invented a newand useful Improvement in Lounges, of

which-the following is a specification.

partly broken away to show the interior. Fig.

2 is a plan View of the same, and Fig. 3 is a detail view of myratchet-and-pawl attach: ment.

A represents the frame of the lounge, provided with four pairs of legs,13, firmly secured to it-two pairs at the head and two pairs at thefoot. (See Fig. 1, showing one side of the lounge.)

G is the bed-frame, of the same width and length as lounge-frame, andresting thereon to form a finish flush with the same all around.

D is the head portion of the bed frame, hinged to it at E to raise andlower. F F are two arched braces, having rack-teeth, and pivoted attheir upper ends to the head portion, and adapted to be raised orlowered at their lower ends to disengage or engage two stoppins, G,fixed in the bed-frame for the pur pose of holding the head portion atany re quired angle of elevation.

H represents four metallic racks, secured at their upper ends to theinner corners of the bed-frame G. v

I represents four pinions, mounted rigidly on two shafts, J, engagingthe four racks, H, to raise or lower them.

K represents four latches, of peculiar construction andoperatiomengaging the fourpinions, I, to hold them from being revolvedby the weight of the racks and their load. Each of these latches isprovided with teeth at both ends, and may be reversed on its pivot toengage either end with its pinion. When the smaller end engages thepinion, the pinion cannot be turned either way; but when the (N0 model.)

large end is engaged the pinion may be turned to raise the bed, but notto lower it. The weighted end tends to keep either end engaged. One endof the head-shaft J is squared, and a cranked socket-wrench, M, isfitted thereto, to be put on or off at pleasure. This wrench has a largecylindrical hub, N, upon which an arm, 0, secured to latch-rod P, mayrest, (see dotted lines, Fig. 2,) to keep the latches disengaged, sothat the bed may be either raised or lowered so long as the wrench.

is on the shaft; but the latches will be free to engage their pinionswhen the crank is removed. VVhen the crank is on the shaft and the heavyends of the latches engage their pinions, the bed may be raised by thecrank, but cannot be lowered. The two latches K are connected by acrooked shaft, R, which is provided with a handle, R, which maybe'reached from the head of the lounge for convenience in someoperations. These two latches serve to prevent the descent of the bed,both at the head and the foot of the lounge, by means of thefollowing-described connections: The two shafts J are provided wit-hsprocket-wheels Q, upon which a chain belt, S, runs to communicate themotion of the head-shaft to the footshaft, so that both head and foot ofthe bed may be raised and lowered together. II are two racks, providedwith feet to stand on the floor. They are engaged by two pin-ions, U, ona shaft, V, which has its hearings in, the lounge-frame, and is squaredat one or both ends, to be turned by the socket-wrench before described.XVhen the shaft V is turned one way, its pinions U climb the racks,thereby lifting the foot of the lounge from the floor until the desiredangle of elevation is attained, when latches XV on rod X, engaging thepin ions, hold the foot of the lounge in position on the racks 'as legs.Y Y are two stirrupbars sliding into the foot of the bed-frame, to beconcealed when not in use, and sliding out to any required distance toextend the stirrups Z, attached to the ends of their extensions Z, toany required distance. The under side of each stirrup-bar is notchedlike a rack, to engage a stud, a, fixed in the bedframe. These racks arefirst raised to disengage them from the studs, then slid out or in tothe required position and allowed to rest in the nearest notch on thestud, their rear ends prying over said studs as a i'ulcra to restagainst the bed-frame. The StlEFIlP-OKiLCJlSlOHS Z are loosely pivotedat (Z to their respective bars, and provided each with a iixed pin, 2),adapted to register with a semicircle of pin-holes, c, in the bar. Thepivot d, fitting loosely, allows the outer end of the extension to heraised to disengage the pin I) from its hole. Then the extension may beturned to the angle required and allowed to rest its pin in the nearesthole to hold it at that angle. These stirrups Z are used to fasten thefeet of the patient to, for dilierent purposes, and their longitudinaland rotary adjustment is to adapt them to the various requirements forthat purpose. Each stirrup Z is shaped as shown in the drawings, havinga cylindrical neck passing through a slot in extension Z, and a T-shaped head to engage cross-notches in the under side of the extension.When the stirrup stands vertically, its head is disengaged from saidnotches; but when pushed forward its shouldcnresting on the top of theextension, causes the head to pry into a pair of notches. e is a shelfhinged to the bed-frame, to hang over and cover the stirrups when pushedinto the bed-frame. It is raised by the act of drawing out the stirrups,is supported on their bars, and in this position serves as a shelf onwhich the surgeon may place his instruments. f is a shelf hinged to thelounge, to swing down flush with the end thereof to form a close finish.It is provided with two legs, y, hinged at their upper ends to the underside of its outer edge. These legs may be folded into a groove in theshelf to conceal them when not in use, or they may he stood verticallyon the floor to support the outer edge of the shelf. This shelf, when sosupported, may be used as a foot-rest for the patient, or as a fixedsteel for the surgeon to kneel upon in operations requiring such aposition.

\Vhat I claim as my invention, and wish to secure by Letters Patent, is-

1. A shaft shaped at its end to be engaged by a wrench, and providedwith a toothed wheel, and a frame in which said shaft is journaled, incombination with a latch pivoted to k said frame, having teeth to engagesaid wheel, a wrench having a hub shaped to engage the end of saidshalt, as described, and an arm secured to said latch to engage saidhub, sub stantially as described, whereby the said latch will berestrained from engaging the wheel by the wrench when the latter is inplace on the shaft, but will be free to engage said wheel when thewrench is removed.

2. The combination, with a lounge having legs at its four corners, ofthe lacks 1, having feet to stand on the floor, and connected to thelounge near its foot-legs, substantially as described, whereby they mayslide vertically, the shaft "8', journaled in the lounge, the pinions U,fixed on said shaft, the latches \V, and the rod X, connecting them,journaled in the lounge, as shown and described.
